I think you fellows are all jumping the gun here a bit regarding Ken's
gearbox with the munched o/d unit.
First of all, Ken has described a relatively low mileage car in which the
overdrive is the problem, not the gearbox. The main shaft has to be replaced
because of the o/d damage, but that sounds to me as though the low mileage
of the gearbox portion (and he'd been driving the car just fine with the
present gearbox) would suggest the rest of the gearbox internals are in good
condition.
Therefore I'd suggest Ken is exactly on the right path in searching for a
tired early 3000 side shift gearbox and o/d unit so he can strip down and
utilize the mainshaft (usually indestructible), replace synchro rings,
bearings and seals while he's in there, retain and reuse all his good gears
into his good gearbox, go through the overdrive renewing bearings and seals
and install that onto his gearbox.
He should end up with a really good complete unit and maintain the
originality and integrity of his low mileage Healey.
For those who have been in there, this is not a difficult job, it's just
lining up good parts and reassembling a proper gearbox and overdrive.
